ATT is no stranger to Windows Phone 7 smartphones. Among US carriers, they offer the broadest selection with 3 models, the Samsung Focus, HTC Surround and LG Quantum. Make that 4 models on June 5 when the HTC HD7S comes out. This is a tweaked an improved version of the HD7 that launched with T-Mobile and overseas carrier. While the HD7 had an old-fashioned basic LCD that looks washed out by today's standards, the HD7S boasts a thoroughly modern Super LCD. It has better color saturation, wider viewing angles and looks as good as its Android cousin, the HTC EVO 4G.

The camera is improved too, with quicker focus and snaps, our other complaint about the original model. Everything else we loved is still here: a super-sized 4.3", 800 x 480 capacitive display, an elegant and extremely slim design, excellent materials with metal and soft touch finishes and a metal kickstand that turns the HD7S into a tabletop video player.

The HD7S is a 3G HSDPA phone that runs Windows Phone 7 with the NoDo update that has copy and paste and an improved Marketplace search among other things. Like all Windows 7 phones, it will eligible for the Mango OS update that brings 500 new features including multi-tasking this fall. The phone has WiFi 802.11n, Bluetooth and a GPS that works with Bing Maps and AT&T Navigator.

Windows Phone 7 may not be selling like hotcakes yet, but we still love the elegant and simple Metro UI. The phone is as friendly and easy to use as the iPhone, and in fact mimics some iOS features such as USB syncing of music using the Zune desktop app (or Windows Phone Connector that hooks you up with your iTunes library on a Mac), and a heavily vetted Marketplace. It also supports DRM and that means not just Zune videos but the ever-popular Netflix.
